the expandable data structure, click on the plus sign (+) available on the left side of the
data structure name, or by double clicking the Name field on the line. To collapse the
whole expansion, click on the minus sign (-) or double click on the line again. If the
Enhanced Array Browsing option is set, the Quick Watch view will show the entire
contents of the expandable data structure by default. To set this option, check the
Enhanced Array Browsing check box in the Edit > Preferences dialog box. If this
option is not set, you can click an expression name to expand that expression to the next
level.
NOTE The expression is of pointer data type, it is expanded only to the next level.
• Memory Log:
The Memory Log feature enables you to save the reports that the Memory Usage view
creates about the data that the debugger collects on your program’s memory leaks and
heap use.
• Enable/Disable Thread:
While debugging a multithreaded application, if you suspect that a specific thread is
causing a problem, suspend other threads in the debugger and debug the thread that
causes the problem. The Enable/Disable Thread feature in WDB GUI enables you to
disable and enable specific threads.
• Steplast support for C and C++:
• This feature, steplast, will step into a function, but not into the calls for evaluating
arguments. In general, if a function call has arguments,which makes further function
calls, the step command will step into argument evaluation call.
NOTE The Steplast feature is supported in WDB GUI with HP WDB version
3.1.5 or higher.
• Support for configuring display of string characters:
WDB GUI allows you to configure the number of string characters or array elements to be
displayed in the LocalVariables/Watch/ QuickWatch views. Lower values can mean less
memory is consumed while displaying large data structures. The default value is 200. You
can set the value to a number between 0 and 1700 in the "Maximum Array Elements to be
printed" text box using Edit > Preferences menu. However, to optimize memory
consumption of WDB GUI, it is recommended that you keep this number as small as
needed for your debugging session.
• Shell commands:
